seen most clearly in. Fig, t, swing the latch bar 136 aside from the lever 129 when the frame 18 siid upon the rails 88, 43, into ope *ative position, permitting said lever 129 to be actuated by the lug 131, the outer end of said latch bar sliding, upon a bracket 139, against a stop-pin 1 10. M1 (Fig. 1) is a. spring adapted to turn said bar back to latching position, where its end face in position. to abut the lever 129, when the frame 18 and cover are withdrawn.

For drivingthe star-wheel 126, a pin 1 12 (liigsf'l, 3 and 12) is mounted between the forks of a. bracket 143 secured to the nearest of the cam members 01, said pin being adapted to engage one of the arms oii'the star-wheel near the end of the upward movement of the platform 28.

For driving the ratchet 1%". a plate 141 formed with a latching; shoulder 1-15 and a driving shoulder 14-6 on its outer periphery, as shown clearly in Figs. 13 and 11, is rotatably mounted upon the shaft 114 and provided with a pawl 1 17 backed by a spring 1 19 is a lever secured to said plate and having its outer end connected by a turu-lmcklc 150 and a. spring 151 with the ampcr end of the rack cylinder 94s 1 and 2), said spring being of sutlicient strength to turn the shaft 114-. 149 is a. stop for said lever 1-1-0. 152 is a hook secured to the top of the rack 36 and adapted upon the descentof the latter to engage the shoulder 1 16 of the plate 1% and thereby turn said plate against the action of the spring 151, the pawl 1 1.7 running free, until the latching shoulder 1415 of said plate passes a lug 153 formed on a latch member 15 oivotcd to the frame of the machine and adapted to ride upon said plate, as shown in Fig. 13. For lifting said latch member to permit said spring to turn the shaft, the rack 36 is formed at its back with a groove 36 adapted to receive alug formed on the latch member 154, the bottom face of said groove being adapted to strike said log and lift. the latch member 15d at the top of the stroke of said rack, releasing the plate 144, as shown in Fig. .1 1. The shaft 114 is provided with a hand wheel 11% (Fig. 1), for tiirning it independently of the automatic driving mechanism, on occasion.

To assure the stopping ot the shaft- 111 in the proper position at the end oi each. cycle of operations, a latching member 156 is secured thereon, (Fig. 1), said member being formed with our notches. apart, on its periphery, said notches being adapted in turn to receive a iatrhing pawl on the end at a spring arm 158 projecting from the frame of the machine, but said notches are formed with sloping sides so that said pawl niiay be dislodged by forcible turning'ozt the s left.

\Vith the construction shown, an air pressure of lbs. to the square inch in both the supply pipes 98 and 102'has been used, and they may therefore lead from a. single source,

but it is desirable that the pipe 102 for the.

ejector be of substantial length, of large capacity, or equipped with a storage reservoir be too quickly reduced by the escape of 'air through the eject0r.

Operation.

The frame 18 is withdrawn, upon the rails in order that the pressure therein may not 38, 3S and 43, and the quarter 10 is placed slid back into operative position, its car 48 striking the arm 138 of the pivot post 137, thereby swinging the latching bar 136 out p of the way of the lever 129. The cover 132 is then slid back over the machine, its lug 131 striking said level 120 and, through the pawl 12S, turning the shaft 114 through 21 At the beginning of this movement of said shaft, the distributor valve disc 113 is in the position shown in Fig. 9; the control valve 96 is in the position shown in Fig.11,

the elevator cylindcr 26 being exhausted through the pipes 111, 112, and the port 105 of the valve actuating pipe 105 being in registry with one of the exhaust grooves of said disc; the rack 36 is in its lowermost p0siti0n,-the bottom of its cylinder 94 being exhausted through the pipe 106 and the exhaust 107 of the distributor valve, thev port 106 of said pipe being rcgisterd with one of the exhaust grooves 113; the upper part of said rack cylinder is charged, the port 10% of the pipe 104 being registered with one of the orts 113' ofsaid valve disc; and the semi-0y indrical rollers are without suction, as the slide-disc 122 in the control 'alve 96 (Fig. 11) shuts off the supply pipe 102 from the ejector 97.

This first movement of the shaft 114 so turns the distributor-valve disc 113 as to register its adjacent port 113' with the port 105' of the control-y ive-actuating pipe 105.

thereby lifting the sli'de valve member 119 of the control-valve 06 (Fig. 11), connecting the sup y pipe 102 with the ejector 97, und

thereb; creating a suction in the sem1-c lindrical rolls; said s'lldm -valve member 119 also lifts the poppet-Va ve member'116,

At the same time pressure from the the ooppe't vah 'e member 116, exhaustingthe elevator cylinder and thereby permit-- ting the platform 28 to descend under its own Weight and the pull of the spring 49.
